The **Kronobat PE-80-EFB** with EFB technology delivers the **80 Ah** at **12 V** and **800 A** of cold cranking current (EN) that cars with Start-Stop, regenerative braking and heavy electrical loads need. It replaces the original battery without adaptation in Start-Stop cars with a 315 × 175 × 190 mm format: same 80 Ah capacity and the positive terminal on the right.
- EFB technology: reinforced electrolyte for many more start cycles.
- Withstands hundreds of starts a day without degrading.
- Compatible with regenerative braking and energy management (BMS).
- Up to three times the cycles of a conventional battery.

### Size, terminals and hold-down of the Kronobat PE-80-EFB

In terms of format, the Kronobat PE-80-EFB measures 315 × 175 × 190 mm (length × width × height) and weighs 21.30 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses 1.0 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### What the Kronobat PE-80-EFB is for

With 80 Ah, the Kronobat PE-80-EFB is the replacement for cars with Start-Stop, regenerative braking and heavy electrical loads. After the swap it may be necessary to register the new battery in the ECU so that energy management works correctly. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 21.30 kg and 1.0 terminals.

### The Kronobat PE-80-EFB: Premium EFB range and EFB technology

The **Premium EFB** is the Kronobat range the PE-80-EFB belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
An EFB is a reinforced flooded battery: its plates retain the active material better and tolerate the cycling imposed by a simple Start-Stop system, at a lower cost than an AGM.

### Why choose Kronobat batteries

Kronobat is the exclusive brand of baterias.com: batteries made to the same production standards as the leading brands, with a value for money that is hard to match and an official warranty. We guarantee that every Kronobat arrives new, charged and with the manufacturer's full warranty.

### Manufacturer's warranty

The Kronobat PE-80-EFB comes with the **manufacturer's official warranty**. To keep it valid, always fit the same technology as the original battery (AGM or EFB) and register the replacement if your vehicle requires it.

### How to make it last longer

A charger with an EFB or smart conventional mode is enough; avoid the high-voltage modes intended for AGM. If the vehicle only does very short trips, a periodic maintenance charge with an AGM/EFB-compatible charger greatly extends its life.

### Shipping, delivery and returns

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### Is the Kronobat PE-80-EFB an EFB battery? When is EFB used?

Yes. The PE-80-EFB is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. Withstands more cycles than a conventional but fewer than an AGM. Fitted to cars with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years.

### Is this battery compatible with Start-Stop systems?

Yes. As EFB technology it is designed for Start-Stop vehicles. EFB batteries cover basic Start-Stop (no regenerative braking). EFB is recommended for basic Start-Stop; AGM is recommended when regenerative braking is also present, thanks to its higher cycle capability. It works straight out of the box — on most modern vehicles registering the battery via OBD is recommended so the alternator automatically applies the optimal charging profile.

### How is the Kronobat PE-80-EFB battery installed in the vehicle?

In most cars it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — with positive on the right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### What is the service life of the PE-80-EFB model?

Expected lifespan of the Kronobat PE-80-EFB is 4 to 6 years in basic Start-Stop car use. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What size is this battery?

Dimensions (length × width × height) are 315×175×190 mm — also written as 315x175x190 mm and correspond to the European L4 case size — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### What polarity does the Kronobat PE-80-EFB battery have?

Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Does this battery fit my car?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The PE-80-EFB typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Kronobat PE-80-EFB?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop cars. See the "Equivalents" section to view recommended options at the same performance level.

### What exactly is an EFB battery like the Kronobat PE-80-EFB?

An EFB (Enhanced Flooded Battery) is a flooded lead-acid battery reinforced with plate additives (carbon and polyethylene) and thicker grids. It withstands twice the cycles of a conventional battery and handles deep discharges better, but less than an AGM. It is the original fitment on cars with basic Start-Stop (no regenerative braking): Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG, Ford EcoBoost. If your car came with EFB from the factory, this is the correct battery — upgrading to AGM is optional (marginal improvement). If it came with AGM, EFB may fall short: better fit AGM. The Kronobat PE-80-EFB is original and meets EN 50342-6.

### Do I need to register the Kronobat PE-80-EFB on the car after installation?

On most cars it is not strictly necessary — the alternator detects the new battery and adapts the charge automatically. It is recommended to register the battery via OBD so that the alternator applies the optimal charging profile from the first minute and extends the battery life as much as possible (especially on brands with sophisticated BMS: BMW, Mercedes, Audi, Volvo, Land Rover). Any workshop with an OBD scanner (~10-15 € labour) does it in 5 minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register, the car will still start correctly — the alternator just takes a few days to adjust the profile. The Kronobat PE-80-EFB ships factory-charged at 80-90% so you can use it straight after fitting.
